(1) TTW model gave the same effect as TPS, but TTW model was better than conventional and TPS model gave the same effect as conventional. (2) For all types of students mind style gave the same effect for mathematics learning achievement of students. (3) In each model of learning, students with mind style types concrete sequential, abstract sequential, concrete random, or abstract random have the same effect for mathematics learning achievement.
